Abstract
A bladed disk assembly includes a rotor disk having an axial dovetail slot, and a rotor blade having a dovetail disposed in the slot. A blade retainer is fixedly joined to the disk for retaining the dovetail in the slot. A spacer is disposed in the slot between the blade retainer and the dovetail and is selectively compressible for allowing the dovetail to slide in the slot toward the blade retainer for generating friction forces to dissipate energy upon impact of a predeterminedly sized foreign object.
